RECORD JACKET MAKING MACHINE BACKGROUND OF THE INVENTION 1. Field of the Search The present invention relates to an automatic record jacket making machine having one or two pockets which jacket is formed from two separated paperboard blanks.

2. Prior Art Heretofore it has been known in the prior art to provide machinery for forming single pocket phonograph record jackets. In this instance machines were provided which could accommodate a paperboard blank of uniform thickness which would act as a folding and gluing machine. These machines, operating at low production levels, would generally form a single pocket jacket of acceptable quality but with the advent of multiple phonograph records in a single jacket these machines could not be used.

The record industry required newer forms of record jackets which could house one or two records and which jacket would have sufficient printing space to permit a higher degree of descriptive verbiage to aid in the sales promotion of the records.

Further, machines for making record jackets, which were available could not handle two different thicknesses of paperboard which would be used to form a single jacket. In most cases, the jackets which were made were formed from a single paperboard folded appropriately to form one or more pockets. This particular method produced an expensive jacket of generally poor quality and the machines had low level production rates. Moreover, because of the machinery used in making these jackets from a single sheet of paperboard, the jacket produced did not close properly creating all sorts of problems, not the least of which was stacking and storage. The machinery previously used also could not provide the proper registry of folded sides because of the nature of the folding and scoring mechanisms employed and, therefore, unsightly record jackets were produced.

ln an industry which promotes various art forms, the packages (record jackets) which formed an important part of the sales promotion did not meet the aesthetic requirements of the record industry.

It was also thought that record jackets of high quality could be produced at a lower cost and at the same time improve the quality of the product.

SUMMARY OF THE INVENTION It is the general object of the present invention to avoid and overcome the deficiencies of prior art record jacket forming machines by providing a unique arrangement of parts which will permit the forming of a one or two pocket record jacket from two independent paperboard blanks.

Another object of the present invention is to provide a machine for making record jackets from different thickness paperboard blanks.

A further object of the present invention is to provide a machine which will sequentially form a record jacket having one or two pockets.

Yet another object of the present invention is to provide a record jacket making machine which will produce record jackets with one or two pockets at a very high production rate.

Still another object of the present invention is to provide a record jacket making machine which will produce record jackets of high quality where the paperboard blanks which form the jacket are folded shut to permit easy stacking of the completed jackets.

Another object of the present invention is to provide a record jacket making machine whereby one or two pocket record jackets may be made by substantially simultaneously feeding independent paperboard blanks on aligned conveyor systems, which are synchronized, from opposite ends of the machine such that record jackets may be formed and folded.

A further object of the present invention is to provide a machine which will completely form and fold, ready for stacking, record jackets having one or two pockets, from two independent paperboard blanks.

Yet a further object of the present invention is to provide a machine for making one or two pocket record jackets from two independent paperboard blanks which are sequentially fed from different points on a carriage and formed on the same carriage.

Still a further object of the present invention is to provide a record jacket making machine which will permit a transverse section for folding and stacking record jackets.

BRIEF DESCRIPTION OF THE INVENTION The foregoing and other objects of the present invention which will become more apparent as the description proceeds are achieved by providing an elongated machine carriage having feeding stations at each end thereof. A laterally extending carriage is connected to the elongated carriage providing a third path of travel synchronized to the feeding of independent first and second paperboard blanks being fed in opposite aligned directions from the opposite ends of the elongated carriage. The first paperboard blank is first fed to a die cutter where notches are formed in the outer longitudinal edges of the blank and thereafter transported to a second die scoring station where score line defining the glue flaps are formed. Having formed and defined the glue flaps the first blank is conveyed to the first folding station where means are provided to fold the flaps inwardly over the blank to creat glue flaps and where adhesive is applied to the upwardly facing surfaces of the glue flaps. The second paperboard blank, which may be of different thickness, is fed from the opposite end of the elongated carriage and is synchronized with and in alignment with the movement of the first blank onto a drum which rotates the second blank into position atop the glue flaps of the first blank in perfect alignment with the first blank. The joined blanks thereafter follow the same path of travel as the first blank and are conveyed abruptly transversely onto the laterally extending carriage to a spine scoring station where dies cut score lines in the joined blanks and a detent is formed between the score lines. The joined blanks are then fed by conveyor through a second folding station where one half the jacket is urged degrees into a completely folded, closed position in which condition the record jacket is moved to a delivery station where the jacket may be stacked and/or packed.

DESCRIPTION OF THE PREFERRED EMBODIMENT The record jacket machine which comprises the invention herein is shown in its unitary form in FIGS. 1 and 2 and may be generally indicated by the reference numeral 25. Further, before describing in detail the structure of the overall machinery the schematic diagram of FIG. 3 should be examined and explained to more fully understand the various working stations of the record jacket making machine or machine 25.

In reality the machine 25 has three ends. Two of the three ends may be termed an input ends while the third end may be termed output end or the delivery end. At the delivery end 26 a complete, printed folded and stacked record jacket is delivered. At the first input end 28 there is provided a first feeding station 50 while at the second input end 30 there is provided a second feeding station 300. Two record jacket blanks feed in opposite directions but in longitudinal alignment with each other and are joined and then transmitted to the delivery end 26 of the machine 25.

As shown in FIG. 3, first feeding station 50 feeds the blank rectangular shaped first paperboard 32, to the notching station 100 at which point there is provided in the first blank 32 a pair of notches 34. After the first blank 32 has been notched the blank 32 moves along a conveyor system 36 to a scoring station where scorelines 38 are cut into the blank 32 at appropriate positions. It should be noted that the first blank 32 is wider by approximately two inches in width than that of the finished jacket. The purpose of this added dimension will become apparent as the description of the preferred embodiment proceeds. The notched and scored blank 32 may be moved to the first folding station 200 where the outer edges 40 of the notched and scored blank are folded inwardly and back onto the main body 42 of the blank 32 along the score lines 38. In this manner, glue flaps 44 are formed. Moving along the elongated carriage 46 of the machine 25 the blank 32 has glue applied to the flaps 44 which have been folded inwardly. While the first blank 32 is being fed from the first feed station 50 longitudinaly along the elongated carriage46 from station to station, a second blank 48 in axial alignment with the first blank conveyor system 36 is fed from the second feed station 300 in the opposite direction of the travel of the first blank 32, but in axial alignment therewith.

The two blanks 32, 48 come together and are joined at the assembly station 250 at which point the second blank 48 is laid atop the first blank 32 and is glued thereto. After the joining of first and second blanks the roughly formed record jacket is moved in the same direction as the first blank to the transfer station-400 at which point the direction of travel of the roughly formed jacket is changed to a motion transverse to the axial movement previously described and the roughly formed jacket is moved, to where a spine 49 is formed. After the jacket is fed to the spine scoring station 450 the ends of the roughly formed jacket are trimmed at the trim station 500 and thereafter moved to the second folding station 550 where the trimmed and spined jacket is folded into a record jacket to be stacked at the delivery end 26 of the machine 25.

Each station and its formal relationship with its succeeding and preceding stations will be hereinafter described in greater detail with appropriate reference numeral designation. This preceding description was merely for the purpose of setting forth in a very general manner the overall operation and function of the machine so that the more detailed description to follow will be more readily understandable.

FIRST FEEDING STATION The first feed station 50 appears at the left hand side of the elongated carriage 46 (shown in FIG. 1) of the machine 25 and is more fully shown in FIGS. 4 and 5 herein. The first paperboard blanks or first blanks 32 are stacked in stacks 52 substantially vertical along a pair of feed belts 54 such that they lean against the inclined surface of a stack support member 56.

The first blank 32 is generally rectangular in shape with its length being approximately twice the diameter of the record to be contained within the finished jacket. However, the width of the first blank 32 is somewhat larger than the diameter of the record to be housed within the finished product. Each of the stacked paperboards first blanks 32 may be of any thickness from 9pts. to 30pts. and the stack 52 is held in feeding position on the belts 54 by the upper and lower guide members 58 as well as stack support member 56 to insure that each first blank 32 is fed to the position against the stack support member 56. As shown in FIG. 5, the

right-hand-most first blank 32 in the stack is in position to be rolled upwardly and forwardly by a rotating cylinder 60 and the action of a pair of suction cups 62. The pair of suction cups 62 which are cam operated into position are adapted to engage each first blank 32 and to pull the first blank 32 forwardly as shown in FIG. 5. The suction cups 62 are moved into position by the operation of a cam arrangement 64 and the cups receive the vacuum suction via hose 63 and pull a first blank 32 forwardly and upwardly over the rotatable cylinder 60 onto a feed slide mechanism 66. As the cam 68 rotates the suction cups 62 are moved into position against the first in line paperboard blank 32. The continued rotation of the rotating cylinder 60 operates to remove the first blank and 32 from the stack 52. The rotating cylinder 60 further operates to move the first blank 32 upwardly and over the rotating cylinder 60. The cam arrangement 64 is linked to the feed belts 54 via the linkage arrangement 70 so that the feed belts 54 are jogged to maintain the movement of the blanks down the inclined belts 54 to the support member 56. As the first blank 32 is moved upwardly and forwardly somewhat over the rotating cylinder 60, a rotating member 72 is in the form of a partial wheel is provided with a leading edge 74 which catches the upper edge 76 of the first blank 32 and serves to bend the blank downwardly over the rotating cylinder 60 so that the first blank 32 as it is urged upwardly by the rotation of the cylinder 60 and pulled forwardly by suction cups 62 and downwardly by the leading edge 74 is directed beneath a guide plate 78 and onto the feed plate 80. A rotating idler 82 maintained over the feed plate 80 moves the first blank 32 onto a conveyor arrangement 84 for the movement of the first blank 32 to the notching station 100.

At the bottom of the inclined feed plate 80 a pair of guide elements 86 guide the first blank 32 onto the conveyor arrangement 84 such that the formerly upper edge 76 of the first blank 32 in the stack 52 abuts against a pair of upwardly extending ears 88 which are periodically rotated to their upwardly extending position by the operation of a pair of link chain drive members 90, 92 which comprises the essence of the conveyor arrangement 84. The guide elements 86 maintain the first blank 32 in longitudinal alignment with the elongated carriage, while an adjustable top guide 87 and spring guide 89 hold the blank onto the conveyor 84.

In order to insure the abutment of the upper edge 76 of the first blank 32 against the cars 88 a drive wheel 94 is positioned at the bottom of the inclined feed plate 80 to insure the movement of the first blank 32 onto the conveyor 84 against the cars 88 in position between the guide elements 86.

This initial alignment of the first blank 32 between the first feed station 50 and the notching station 100 is important because the succeeding sequence of operations are synchronized thereto.

NOTCHING STATION The first blank 32 is fed by the two drive wheels 94 and fed between a pair of guide elements 86 onto the conveyor 84. The conveyor 84 is periodically interrupted by a pair of stop members or ears 88 such that the first blank 32 is pushed along from its rearward edge 101 by stop members or ears 88. The ears 88 which push the first blank 32 along the conveyor systern 84 between the guides 86 also act as a point of synchronization for the second blank which is being fed from the opposite feed end of the carrier.

In order to form the notches 34, which is the preliminary step in the formation of the glue flaps 44 as well as the division of the first blank 32, a conveyor wheel 102 rotates in synchronized movement with the feed conveyor 84 such that the rotation thereof guides the first blank 32 over the rotating notch forming knife arrangement 104. A second wheel 106 is rotatable immediately below the conveyor wheel 102 and the cooperative movement of the wheels 102,106 forms the notch 34 in the approximate center of the side edges 108 of the first blank 32. As shown in FIG. 9, the conveyor wheel 102 and cutting wheel or second wheel 106 are positioned in vertical alignment such that the conveyor wheel 102 provides the downward pressure against the first blank 32 and forces the same downwardly into cutting arrangement with a cutting die 1 10 disposed in the outer periphery 112 of the cutting wheel 106.

As shown in FIG. 8, the notch 34 formed in the outer edges 108 of the first blank 32 takes a particular shape which the cutting edge 114 of cutting die is adapted to form. FIG. 10 shows the cutting of the inner most edges 116 of the notch 34 by the cutting die 110 on the cutting wheel 106. It should be noted that two cutting wheels 106 are provided such that the notch 34 is cut in both side edges 108 of the first blank 32. At each side edge 108, a rotating notch forming knife arrangement 104 is provided so that a notch 34 is cut in the upper side edge 118 of the first blank 32 and the lower side edge 120 of the first blank 32. Both conveyor wheels 102 are connected for synchronous rotation by an axle 122 and both cutting wheels 106 are connected by an axle 124. Both axles are driven by an appropriate drive shaft 125 as shown in FIG. 1 from which drive shaft 125 all rollers, feed mechanisms and conveyors are driven through appropriate bevel gears. The drive shaft 125 is driven by a main motor (not shown).

SCORING STATION The first step in the formation of the record jacket is thereupon completed by the forming of the notches 34 in the upper side edge 118 and the lower side edge 120 of the first blank 32. In order to form the glue flaps 44 at the upper and lower edges of the first blank 32 which will form the surfaces 152 to receive adhesive, a pair of score wheels 154 are disposed across the elongated carriage 46 of the bed of the machine 25. The first blank 32 which has been notched is fed along the conveyor arrangement 84 to another conveyor arrangement 156 in spaced alignment relationship the first conveyor 84 such that the notched first blank 32 is moved between side guides 158 to a position beneath a pair of scoring wheels 162 which are rotatable against the first blank 32 along the length of the first blank 32 at a point inward of the upper and lower side edges.

The formation of score lines defines the area of the glue flaps 44 and since glue flaps 44 must be formed at the upper and lower sides of the blank 32, two scoring arrangements 162 must be provided to form the upper score line 164 and lower score line 166. Each scoring arrangement 162 is formed by two wheels. A first wheel 168 is positioned above a second wheel 170 much the same as at the notching station 100. Each scoring arrangement 162 is provided with the male score forming member 172 formed on the outer periphery 174 of the second wheel 170 below the first blank 32 and the female score member 176 provided above the first blank 32 on the outer periphery 178 of the first wheel 168. Since the score lines 164, 166 run the entire length of the first blank 32 and the glue flaps 44 are defined by the scores 164, 166 and notches 34 and'may easily fold upwardly along the score lines to form the folded glue flaps 44. However, the function of the scores provided inwardly of the upper end and lower edges of the first blank 32 is to permit the folding upwardly and inwardly, back onto the main portion of the blank 32, the guide flaps 44 which will retain their folded over characteristics to further permit the easy application of adhesive thereto.

The conveyor system 156 of the scoring station 150 is the same conveyor mechanism which moves the notched and scored first blank 32 along the longitudinal path of travel atop the elongated carriage 46 of the machine 25 and thereafter to the folding first station 200.

It should be noted that the movement of the two wheels 168 and the two wheels 170 are synchronized together by means of shafts 180 which are operated from a drive means 125 which is well known to those skilled in the art.

SECOND FOLDING STATION As shown in FIGS. 13 and 14 the first folding station 200 is comprised of a set of curved and formed metal members 202 which are positioned parallel to the longitudinal axis of the elongated carriage 46 of the machine 25. Each member 202 is positioned in the path of the upper and lower side edges 118, 120 of the first blank 32. Each member 202 provides a flat section 204 (at left in FIG. 13) whereafter the outer section 206 of each member is bent gradually upwardly or downwardly as the member 202 extends along the elongated carriage 46 until the outer section 206 begins to bend the flap 44 toward the center of the first blank as shown in FIG. 14. Therefore, as the notched scored first blank 32 moves against the fold forming metal strips 202, the flaps 44 which are formed by the score lines 164, 166 and notches 34 fold upwardly and then inwardly toward the center of the first blank 32 and there are formed four glue flaps 44, each of which is bent inwardly along the score lines 164, 166 of the first blank. As shown in FIG. 14, the first blank 32 folds upwardly along the score line such that a rib 210 is formed and faces inwardly towards the center of the first blank 32.

Because of the nature of the paperboard itself when the glue flaps 44 are formed and folded over inwardly toward the main body of the first blank 32 the flaps 44 have a tendency to rise upwardly over the board because the board has not been sufficiently broken for the flaps 44 to stay down in their folded condition. In order to insure that the flaps 44 stay down and do not unfold, a glue applying pressure roller 212 is provided on each side of the elongated carriage 46 and in alignment with the partially folded over glue flaps 44 to force the glued coated flaps downwardly under pressure so that each glue flap 44 may receive on its upwardly facing surface 214 a measure of adhesive 216.

GLUING STATION After the glue flaps 44 have been formed so that the glue surfaces 214 have been created and face upwardly from the conveyor belt arrangement 156 along which the notched, scored and folded first blank 32 has moved, an adhesive is applied to the upwardly facing surfaces 214 of the glue flaps 44. As shown in FIGS. 15 and 16 the flaps 44 ride beneath the glue applying pressure rollers 212 and a measure of glue 216 is applied to the upwardly facing surface 214 of each flap from a glue pot 213. The adhesive to be used may take any appropriate formulation well known to those skilled in the art and as such forms no part of the invention per se. It should be understood, however, that a means of adhesion is applied to the upwardly facing surfaces 214 of glue flaps 44 to form adhesion surfaces which will be hereinafter joined to a second paperboard blank 48.

SECOND FEED STATION At the opposite end of the elongated carriage 46 there is provided a second feeding station 300 at which is similar in structure to the first feeding station 50 and which feeds the second paperboard or second blank 48 onto a conveyor system 302 in synchronization with the movement of the first paperboard blank 32. The second feeding station 300 is a mirror image of the first feeding station 50 and the second blank 48 is fed onto a conveyor chain link belt 304 having upwardly extending ears 306 thereon. The conveyor arrangement shown in FIG. 17 takes the form of a chain-link belt 304 in combination with a pair of rotating drive wheels 308. The second feeding station 300 and drive wheels 308 thereof moves the second blank 48 onto the conveyor arrangement 302 such that the upwardly extending ears 306 engage the rear edge 310 of the second blank 48 and push the second blank 48 along the system until the leading edge 312 of the second blank 48 is urged between a pair of rollers 316 and then onto joiner drum 318.

The size of the second blank 48 is important to note. Before second blanks 48 are stacked in the second feeding station 300 the blanks are precut to the approximate dimensions of the notched, scored and folded first blank 32.

It is important to note that the movement of the second blank 48 is timed such that they will join at the proper moment at the joiner drum 318 so that the top surface 320 of the second blank 48 may be inverted on the joiner drum 318 to be the inner surfaces of the pockets to be formed in the roughly formed record jackets which immerge from the assembly station 350.

ASSEMBLY STATION It should be further noted that an additional gluing operation may be achieved at the assembly station 350 in the event it is decided that the finished record jacket shall provide only one pocket rather than two pockets.

In such event a glue roller 352 with an adhesive applicator 354 is provided at the assembly station 350 and which applicator 354 is fed by means of a roller 356 which is partially emmersed in a glue well 358 and which well 358 may be fed manually or automatically with glue.

At the assembly station 350 the first blank 32 in its notched, scored and folded and glue applied condition and the second blank 48 are joined together. The first blank 32 with its glue flaps 44 having glue applied to the upwardly facing surfaces 214 is fed between a pair of guide elements 360 and is moved into position beneath the joiner drum 318 by means of a pair of rollers 362. Simultaneously, with the movement of the first blank 32 toward its position beneath and tangential to the outer periphery of the drum 318, the second blank 48 is being conveyed to a position 366 tangential to the outer periphery 364 of the joiner drum 318 at which point a gripping roller 370 engages the front edge 312 or the second blank 48 and the second blank 48 is thereafter rolled around the outer periphery 364 of the joiner drurn 318 between the periphery 364 thereof and a curved guide plate 372. The construction of the joiner drum 318 is such as to provide for vacuum ports 365 in the periphery 364 of the hollow drum. The vacuum enters the drum interior via the hollow shaft 319 from a vacuum source not shown.

During the rotation of the joiner drum 318, the second blank 48 moves with the drum 318 by virtue of the vacuum through ports 365 in a counter-clockwise motion until the leading edge 312 of the second blank 48 and the leading edge 374 of the first blank meet and are both tangential to the peripherial surface of the joiner drum 180 from the original tangential position 366 of the second paperboard blank 48. At this point the leading edge 3112 of the second blank 48 and the leading edge 374 of the first blank 32 are in approximate alignment while the side edges of the first blank 32 (in its folded condition) and the second blank 48 are in absolute alignment, one atop the other, as shown in FIG. 17, At the position where the two leading edges are joined, that is, the second blank 48 atop the first blank 32, and in registry therewith, the joined blanks are forced together by the pressure formed between the outer periphery 364 of the joiner drum 318 and the outer periphery 376 of a roller 378 disposed immediately beneath the joiner drum 318. As the joined blanks are moved between the drum 318 and roller 378 the adhesived surfaces will become glued together in alignment one with the other at their side edges and both blanks are thereafter further pressed together between additional rollers 380 and 382 so that all adhesion surfaces are joined under pressure and the roughly formed record jacket 384 is thus formed and thereafter moved to the transfer station 400.

The additional rollers 380 and 382 are positioned across the roughly formed jacket 384 so that additional pressure is applied over the adhesion surfaces. The additional rollers also act to accelerate the roughly formed jacket 384 onto the transfer station.

TRANSFER STATION After the roughly formed jacket 384 is assembled through the action of the joiner drum 318, the roughly formed record jacket 384 follows the same travel path as the first blank 32 along the longitudinal axis of the elongated carriage onto the transfer station. The object of the transfer station is to change the direction of movement of the roughly joined record jacket 384. As the roughly joined jacket passes between the additional rollers 380, 382, it is moved into position above a pair of transversely operating chain link conveyor belts 402 against a stop member 404. The roughly formed jacket 384 is urged against the stop member 404 by means of upper brushes 405 and lower guide rollers 407 at which point the jacket 384 will come to rest momentarily until the movement of the transverse belt 402 takes the jacket 384 in the direction of the transversely operating chain link conveyor 402. As the roughly formed jacket now moves transversely to its original direction it moves down the leg 406 of T-shaped carriage portion and the roughly formed jacket is thereafter fed to the spine forming station 450.

SPINE FORMING STATION As the roughly formed record jacket 384 is moved by the ears 408 on the transversely operating chain link belt 402, the roughly formed jacket 384 passes between a pair of guide members 452 and onto the spine forming station 450. As shown in FIGS. 20 and 21 the roughly formed jacket 384 moves from the transverse conveyor belt 402 to another conveyor belt 454 passing beneath a roller 456 which maintains the roughly formed jacket 384 in position on the conveyor belt 454 so that the same may smoothly travel between the guide members 452 into the spine forming station. In reality the spine forming station 450 and the trimming station 500 are in the same position on the transverse leg 406 of the T-shaped carriage portion.

In order to form the spine generally indicated by the reference numeral 456 there is provided a movable upper die support member 458 having disposed on its lower surface 460 a downwardly extending pair of dies 462. Immediately below the pair of dies 462 there is provided a male die 464 mounted to a fixed lower die support member 465. The cooperating dies 462, 464 form a detent 466 in the two blanks which formed the roughly formed jacket 384. The roughly formed jacket 384 is conveyed to a position between the upper and lower die until the jacket abuts a stop member 468. As shown in FIG. 20 the roughly formed jacket 384 is moved in position against the stop means 468 by means of a pair of ears 470 formed on the conveyor belt 454. The upper die support member 458 is adapted for reciprocating movement against a coil spring 472. The coil spring 472 is mounted around a guide post 473 secured at one end to the upper die support member 458 which passes through an aperture 475 in the lower die support member 465. At its opposite end guide post 473 is affixed to a movable plate 477. Mounted on the moveable plate 477 is a support block 479 which has an elongated shaft 481 passing therethrough. The outer ends of shaft 481 passes through slots in the transverse carriage and have guide blocks 483 affixed to their ends. In order to reciprocate the plate 477 a rotatable shaft 485 is provided with a cam member 487 at the end thereof to effect the reciprocating action of lower plate 477. Guide ways 489 insure the vertical movement of the guide blocks 483 and their associated members. When the roughly formed album jacket 384 is in proper position beneath the upper die support member 458 such that when the dies 462 are brought downwardly against the male die 464 by the operation of the movable plate 477, the movement forms the spine 456 in the roughly formed jackett 384. The formation of the spine 456 is followed by the sequential downward movement of the stop member 468 which is cam operated through the rotating cam arrangement 474. The movement of the cam arrangement 474 is related to the reciprocating movement of the upper die support member 458 so that when the upper die support member 458 is in its higher position the stop 468 is positioned as shown in FIG. 20 to act as a stop against the continued movement of a roughly formed record jacket 384 along the conveyor system 454. With the downward movement of the upper die support member 458 and the concurrent formation of the spine 456 through the action of the pair of dies 462 and the stationary male die 464, the stop 468 is moved downwardly about the pivot point 476 permitting the spined record jacket 384 to move out from beneath the upper die support member 458 and permitting another roughly formed jacket 384 to move into position beneath the upper die support member 458. In this manner, roughly formed record jackets 384 are continuously and synchronously moved into position beneath the upper die support member 458 to have the spine 456 formed in the roughly formed record jacket 384.

TRIM STATION Simultaneously, with the formation of the spine 456, the leading and rear edges 312, 374 of the first and second blanks are trimmed as shown in FIG. 21. It had been previously stated that the first blank 32 and the second blank 48 are joined at the joiner drum 318 at a position located between the joiner drum 318 and the roller 378. In order to insure that the edges, both leading and rear, of the blanks are precisely in alignment, the edges are trimmed by means of the knife arrangement 502 connected to the upper die support member 458. Once the leading and rear edges of the joined first and second blanks have been trimmed the record jacket is now complete except for the folding thereof.

SECOND FOLDING STATION In order to fold the record jacket closed about the spine 456 which had been formed in the spine forming station 500 the completed but unfolded record jacket 384 is moved by the conveyor 454 toward the delivery end 26 of the machine 25. As the record jacket moves toward the delivery end 26 a bar 552 is formed to engage the bottom of the right hand half (as viewed in FIGS. 1 and 21) of the record jacket. As jacket 384 moves the bar 552 bends the aforementioned half of the jacket 384, about the spine 356 onto the left-hand half of the jacket. In this manner, the completed and closed record jacket which comprises the final product 600 is brought to the delivery end 26.

As previously indicated a motor, not shown, drives the main drive shaft 125 upon which are mounted bevel gears for all rollers, feed mechanisms and conveyors along the elongated carriage and transverse leg portion.

While in accordance with the patent status, a preferred embodiment has been shown and described in detail, the invention is not limited thereto or thereby.
